<%@ page isErrorPage="false" %> <%@ page errorPage="error1.jsp" %> <HEAD> <%@ page import="myclasses.*" %> <jsp:useBean id="theo" scope="page" class="TT" /> <% try { theo.computeTitle("hello"); } catch(Exception e) { throw e; } %> <% String title=theo.getTitle(); %> <TITLE><%= title %></TITLE> </HEAD> What is the output to the browser from the code above if the method "computeTitle()" in class TT throws a java.lang.NullPointerException? A blank screen is sent to the browser. No title will be shown. The title will be java.lang.NullPointerException. Only the output of error1.jsp. The Title will be "null" plus the contents of error1.jsp The memory footprint of a JSP page can be measured by serializing the generated JSP Servlet to disk and seeing how large that file is. Which one of the following statements about the above approach is TRUE? This approach is too slow to perform on a live system. The measurement is not accurate. JSP pages do not have access to the Server's hard drive. Serialization will not take into account objects referenced by the JSP page in all cases. JSP pages cannot serialize JSP Servlets.
